2001/2002:Inspection Strategies of Reformer Tubes and

Inspection Strategies of Reformer Tubes and Outlet Components Catalyst tubes in steam reformers are made of high-alloy spun cast materials. Alloys of the past and tubing can be manufactured by centrifugal casting in cast 32/20+Nb and HP-LC materials A Comprehensive Approach to Reformer Tube Inspection Reformer tubes normally used in the refining, petrochemical and fertilizer industries are manufactured by the centrifugal casting process and heat-resistant austenitic alloys such as HK -40, HP-40, and HP -Niobium modified materials. A design life of 100,000 operating hours has been the normal time-based criteria for considering retirement of

Microstructural characterization of modified 25Cr35Ni

Oct 01, 2002 · HP steels modified with Nb and Nb-plus-Ti, produced in the form of centrifugally cast tubes, were characterized by means of light optical microscopy, scanning electron microscopy (SEM) with secondary and backscattered electron imaging, and transmission electron microscopy (TEM) with energy-dispersive spectroscopy (EDS) and selected area diffraction. Microstructure and Carburization Detection in HP Alloy Jun 25, 2015 · Centrifugally cast HP alloy tubes display either a completely columnar structure or a mixed columnar-equiaxed structure, depending on the centrifugal casting conditions (for example, the pouring temperature and the cooling rate) [1315]. The 100% columnar structure of the ex-service tube indicates a high cooling rate induced during casting. Role of Nb in modifying the microstructure of heat Apr 01, 1991 · @article{osti_5062402, title = {Role of Nb in modifying the microstructure of heat-resistant cast HP steel}, author = {Barbela, G D and de Almeida, L H and Silveira, T L and May, I L}, abstractNote = {Heat-resistant cast stainless steels have widespread uses in the petrochemical industry in pyrolysis and reformer furnaces; 25%Cr-20% Ni or 25% CR-33% NI high-carbon steels, designated HK and HP
